Introduction
Geoscience Australia's objectives with the Resourcesat-1 (IRS-P6 mission) was to provide continued remote sensing data services on an operational basis for integrated land and water resources management. No longer available from Geoscience Australia.
Historical information
IRS-P6 is the continuation of the IRS-1C/1D missions. The launch of the satellite took place October 17, 2003. Resourcesat-1 is also known as IRS-P6. IRS-P6 is an Earth observation mission within the Indian Remote-Sensing (IRS) series of satellites operated by the Indian Space Research Organisation (ISRO), Bangalore, India.
Australian Centre for Remote Sensing (ACRES) commenced acquisition of Resourcesat-1 Linear Imaging and Self Scanning sensor (LISS-III) and Advanced Wide Field Sensor (AWiFS) data in February 2008.
The data will be routinely recorded over Australia, although not every pass will be acquired and archived.
Archive data over Australia will be available to Australian and New Zealand residents only. For more information on the availability of Resourcesat-1 data contact Earth Observation Client Services.
Sensor characteristics
Resourcesat-1 (IRS-P6)
The satellite has three sensors on-board:
- a LISS-III sensor
- AWiFS sensor and a high resolution multi-spectral Linear Imaging Self-Scanning Sensor-4 (LISS-IV)
- an On-Board Solid State Recorder (OBSSR).

Only LISS-III and AWiFS data are acquired and distributed by Geoscience Australia.
The LISS-III and AWiFS sensors operate in four spectral bands, three in the visible and near infrared and one in the SWIR (1.55 to 1.7 microns) region.
The LISS-III sensor has radiometric quantisation of 7 bits and provides a combined swath of 141 kilometres with a spatial resolution of 23.5 metres.
The AWiFS sensor has radiometric quantisation of 10 bits and provides a combined swath of 740 kilometres with a spatial resolution of 56 metres at nadir.
All sensors have the feature of on-board detector calibration using LEDs. The sensors can be operated either in Real Time mode by direct transmission to ground station or in Record and Playback mode using an on-board 120 GB capacity Solid State Recorder.
